Costs of a Connection in ! autocommit mode

Are there any costs (viz. in memory usage) incurred by the server when working with a Connection whose autoCommit property is false vs one whose autoCommit property is true? Specifically before any CRUD statement has been issued on the connection.

compare:
DataSource ds = . . .
Connection conAuto = ds.getConnection();
conAuto.setAutoCommit(true);

Connection conTx = ds.getConnection();
conTx.setAutoCommit(false);


In terms of memory costs (or other costs for that matter), do conAuto and conTx consume the same amount of memory overhead on the server? Or does a MySQL server pre-allocate some extra memory for conTx?, sort of a "get ready for a tx"
